in the conference room.

Everyone was lost in thought.

The math content on the whiteboard is very clear, and it is a complex system of partial differential equations, and the difficulty of the problem is very high.

Even one less unknown can be considered a small study.

After adding an unknown number and a relational function, the difficulty of the problem increases exponentially, and if the problem can correspond to a certain field of application, it is enough to apply for a mathematics program at the elite level.

This kind of problem is not easy to solve.

"It's because of the difficulty that Wang Hao let us figure out a way together, right?"

"It may be related to a certain research, but this kind of topic is too difficult to solve, and it is unlikely in a short time......

"With so many of us researching together, we can at least find the direction."

"If this can help, maybe you can also mix up the name of the paper? If it is related to any major application, it is difficult to make a contribution, and in this regard, Wang Hao is not stingy......"

“……”

This is also one of the reasons why Wang Hao has appeal.

In many research fields, as long as you participate in the work of the research group, even if you don't make any contributions, you can at least have a name.

If there is a contribution, it will be recorded in the eucalyptus.

In addition, Wang Hao has completed a lot of major research, and it seems that any problem can be solved in his hands, and everyone likes to do research work with him.

When everyone saw that the topic was about the same, Wang Hao began to explain, as if he was giving a lecture to students, and said, "Let's look at this topic." ”

"A system of partial differential equations has one more relational function than the conventional dynamical equations, that is, one more unknown."

"Such equations are very difficult to solve."

"I'm going to talk about a few common methods here, and everyone will think about it."

"The first is ......"

Wang Hao said seriously.

In the field of partial differential equations, he dared to say that he was the second in the world, but no one dared to say that he was the first, because he solved the NS equation problem in the seven mathematical conjectures of the millennium.

His thinking is also very clear.

When faced with a complex system of partial differential equations, he said five ways in a row to cut into the problem and then change it.

The people in the conference room followed suit.

Some of them are good at solving partial differential equations, such as Ding Zhiqiang, whose main areas are partial differential equations and algebraic geometry.

Some of them have not studied much on partial differential equations, but they have been engaged in high-end scientific research and still understand the idea of solving partial differential equations.

When Wang Hao explained in detail, they were all amazed, and some methods they didn't expect were made, and they all felt that they had gained a lot.

When Wang Hao explained the fifth method, the correct information was fed back in his mind, and his eyes lit up and he stopped talking, and then said, "I just said five ways to cut in, but I personally think that the third method is the most ingenious and the most likely to solve the problem." ”

"Let's come and see ......"

"The constants of these equations are actually related, if we can do a transformation, like this......"

Although he just said to make a change, Wang Hao wrote a blank slate in a row, and then said, "Have you found out?" In the case of the first and fourth methods, this transformation would be problematic, but this method would eliminate the constants of Equations 4 and 5......"

"The equation is simplified."

Everyone nodded in understanding.

When they heard this, they also felt that the third method of entry was a very good choice, but they were not sure whether it would solve the problem.

Wang Hao asked people to bring a new whiteboard and continued to analyze, "Our change just now has eliminated two constants, simplified Equation 4 and Equation 5, and the next step is to do a solution. ”

"It's not an easy step either."

He said that it was not easy, but the pen in his hand did not pause, "We need to substitute Eq. 3 and Eq. 2 to see if we can eliminate an unknown of the main equation." ”

"We continue to transform ......"

Wang Hao explained while analyzing.

Everyone keeps up with the train of thought and understands carefully.

Although Wang Hao's analysis speed is very fast, he has the effect bonus of "The Gift of Teaching", and he can be said to be the top scholars in mathematics, physics, computer and other fields present, and even Zhang Zhiqiang, who has a worse level, understands it.

They nodded frequently as they listened, "That's right, that's it." In this way, substitution may eliminate the unknown. ”

"Makes sense, it's a good idea."

"That's what I thought, that's what I just thought."

“……”

Wang Hao continued to analyze.

His analysis filled a new whiteboard, and finally came up with a function, and then made a simple function diagram so that everyone could see it more clearly.

At this time, the relationship between the three unknowns of the equation has been found.

Many people were stunned.

Paul Phil-Jones was amazed and said, "If you substitute Eq. 1, won't you be able to find the value of γ?" ”

"yes, I've got a value!"

"In the end, to find the functional relationship, the single value of the γ is also very important, and by substituting it into Equation 3, we can get the relationship with the β......"

"Isn't that just a simple question?"

“……”

They discussed in amazement, and suddenly felt that something was wrong.

How did it get to this point?

Doesn't that mean more than half of the problem is solved? The puzzle has become a lot easier, and then keep going...... Isn't that the solution?

Some people who understood it had obviously become very strange, but they continued to follow along to understand.

Wang Hao did not pause.

At this point, the inspiration value has exceeded 90 points, and the direction of solving the problem has been found.

He continued to do the analysis, as if he were giving a lecture to the students, and while he kept explaining, the third whiteboard was full again.

When a new tabula rasa was brought up, he directly on the tabula rasa and summarized the previous content into a simplified system of equations, "From the beginning to the present, the relationship has been sorted out very clearly." ”

"Let's see, this simplified system of equations ......"

"The difficulty of the problem is very high, but if you think about it, you can always think of a solution......

"We continue to ......"

Actually, there is no need to continue at all.

The difficult parts have been solved, and even if Zhang Zhiqiang is allowed to get the rest, he can follow the train of thought to come up with an answer.

The difference is just time.

Wang Hao's problem solving speed is very fast, because the research has been completed, and the inspiration value exceeds 100 points, he no longer continues to explain, and directly begins to write the answer.

After using up the fourth whiteboard, he finally listed the functional relationships between several unknowns such as power, height, speed, etc.

That's the result.

After writing the results, Wang Hao smiled at everyone and said, "Look, let's complete the solution." So when faced with a problem, as long as you think about it, you can always solve it......"

“……”

“……”

The expressions of the people in the conference room were a little numb.

At first, they thought that Wang Hao had encountered a problem, so they asked them to do research together, but after listening for more than an hour, the problem was solved?

Is this Wang Hao's new achievement?

Are you lecturing them?

The gain of this class is indeed not small, at least they understand a lot of methods for solving partial differential equations, but ...... Why does it feel a little wrong?

How did it become a class?

Chen Mengmeng, Zhang Zhiqiang, Luo Dayong and others don't think so, they all know very well that the topic was taken by Mr. Zhou.

As a result, Wang Hao solved it so quickly?

I also gave them a lesson on complex partial differential equations!

"What the hell is this guy's brain?"

"Such a difficult question......"

"If I hadn't seen it with my own eyes, I wouldn't have believed it."

"But what are we here for, just to listen to the lectures? How do I feel weird......"

"It's not a lecture."

Zhang Zhiqiang took a deep breath and said in a conclusive tone, "I feel that this guy asked us all to come over just to see him pretend to be X!" ”

……

Mr. Zhou took a picture of the math content on the whiteboard with his mobile phone, and then embarked on the way back with the 'problem-solving process and answers'.

Along the way, he was a little confused.

Even if he overestimated Wang Hao's ability, he didn't expect such a complex problem to be solved in just over an hour.

The experts of the power group spent more than two weeks doing research without results.

Hao......

More than an hour?

Teacher Zhou returned to the experimental base with shock, and immediately found Ruan Xingping and said, "He is like solving a simple mathematical problem." ”

"The idea has always been very clear, and I wrote the answer from beginning to end, as if I knew how to solve it from the beginning......"

"He also gave a lecture to a group of professors by the way, including Paul Phil, Ding Zhiqiang, Luo Dayong and others......"

“……”

Nguyen Xingping felt like he was listening to a joke, he knew very well how difficult it was to solve the power balance problem, but he couldn't completely disbelieve it.

Teacher Zhou really didn't take long.

He could only look at the content with doubts, and called others to analyze it together, but found it difficult to make a judgment in a short time.

This is mainly due to the complexity of the problem-solving process.

Wang Hao spent more than an hour to explain, and his explanation was very detailed, coupled with the comprehension bonus of "Teaching Feedback", so that the people in the conference room could keep up with the ideas.

The power pack is different.

They look at the content and then understand it.

In addition, their average is relatively poor.

In the Mason Number Laboratory, everyone who can be qualified to participate in Wang Hao's research can be said to be elites, even Zhang Zhiqiang, who is relatively poor, is also a doctoral graduate from a prestigious university, plus so many years of research in the direction of mathematics and computer, the level is naturally not too much different.

Zhang Zhiqiang put it in the power group, how can it be at the middle and upper level.

Therefore, it still takes a lot of time for people in the power group to understand the process, so they simply start from the results and compare the experimental data with the results.

Then it was found that the deviation was very small after substituting the value.

This made the people in the power group feel incredible, and after Ruan Xingping confirmed the result, he sat in his position in a daze and didn't move for a long time.

He began to doubt his life.

The power group is not said to be elite, but they are also related scholars, and the problems that they spent more than two weeks not studying were solved in only one hour when they went to Wang Hao?

An hour was spent mostly on solving problems and explaining.

In other words......

Wang Hao knew how to solve the problem at the beginning, so he just wrote out the process and explained it to the people in the Mason Number Lab.

That's too big a gap!

Teacher Zhou ignored the mood of the power group.

As soon as the power group determined that the process and results were correct, he immediately took up his job and approached the computer team to translate the answers into computer language.

In this way, the electronic system can be automatically calculated, which also solves the biggest problem of the air-ship-2 test stealth technology.

……

At the same time.

International public opinion is still fermenting around the stealth technology of the Air-2.

The overwhelming media reports let everyone know that the Kongjian-2 has a high-end stealth technology that is suspected of 'creating a strong annihilation force field'.

Under such a surging public opinion, some relevant elders also stood up and said, "We are experimenting with a new stealth technology." ”

"This stealth technology is related to annihilation technology."

"But this is just a normal technical experiment, an exploration of high-end technology, which has nothing to do with the international situation and will not threaten ......"

The follow-up doesn't matter.

The relevant elders stood up to confirm the news, which immediately attracted the attention of public opinion.

Although there are a lot of photos and videos on the Internet, and everyone knows the news through speculation and analysis, the statement of the relevant elder is directly qualitative.

For a time, the attention of the Air-2 was even higher.

Of course, those professional organizations are not only concerned with public opinion, but also about the technology contained in it and the threats it can pose.

The technical side is clear.

The air-2 is based on the lateral anti-gravity field, creating a strong annihilation force field of a certain strength, which is not high from the outside.

An expert who has participated in the International Annihilation Theory Organization has assessed, "The inner layer strength is more than 3 times, but it definitely can't reach 4 times." ”

"That's strong enough to annihilate all electromagnetic waves."

"In other words, all radars capable of long-range detection will lose their effectiveness......"

That's the threat.

When the technical analysis is thorough, the threat is real.

Previously, the air-ship-2 was considered to be the aircraft carrier nemesis, because the air-ship-2 can fly high enough to ensure safety, and the bomb load is also very shocking, and it can theoretically cover the aircraft carrier.

However, theories are just theories after all.

The air-ship-2 cannot carry all high-end missiles with locking functions, and missiles without locking functions must be delivered accurately.

Dropping bombs at an altitude of 30,000 meters will have a pitiful low accuracy.

It's different now.

With stealth technology, the air-ship-2 cannot be locked by conventional radar, and there is no need to levitate at high altitudes at all, just hover back and drop bombs overhead.

When the time comes, it's time to accurately cover the blow.

In the face of aircraft that cannot be locked by radar and carry a large number of missiles, the huge aircraft carrier hull has really become a live target.

How to fight it?

The only way they thought of it was to fight with fighter jets, but air-to-air missiles could not lock onto the target, so they had to rely on the pilot's operation.

However, the flexibility of the fighter does not necessarily catch up with the ship-2 in the air.

If the other side makes a surprise attack at night, they will not even have time to react because the radar cannot warn them in advance.

And that's just for aircraft carriers.

"What if the empty ship-2 is on a nuclear bomb delivery mission?"

"The anti-missile system will be completely ineffective, and military bases will become targets, allowing the other side to strike at will......"

"There is no way to defend effectively!"

Everyone was in a cold sweat when they thought about it, and someone couldn't help but suggest, "I think the upcoming exercise plan can be appropriately low-key." ”

"Yes, be low-key."

"They must not be considered a provocation ......"

In fact, there was no need to be a conductor at all, and the person in charge of the exercise, General Witton, had already thought about keeping a low profile, and even directly refused all interviews.

The previous interview was planned.

They conduct open exercises in order to achieve the goal of deterrence, and then let reporters openly cover and shoot pictures to achieve the goal of showing force to the adversary.

It's different now.

When it was learned that the opponent had the ability to form a covering strike on itself, the mentality when launching the exercise was suddenly different.

It's like two people having a conflict, and one party shows strong muscles to the other.

The other party directly pulled out a gun.

What to do?

can only keep a low profile......
